Rule #3: For More than Two Same-Named Individuals, Use Roman Numeral Suffixes. What if there are more than two same-named individuals in the Johnson family? Then, they can use Roman numeral (i.e. I, II, III, IV, etc.) suffixes after their name, to designate the order in which they were born. Rule #4: âSr.â and âJr.â
Search for: Subunit vaccines are vaccines that use only part of the disease-causing virus. This strategy is used most often when one part of the virus is responsible for creating disease. The part responsible for creating disease is a protein, which we call the antigen. An example of the recombinant subunit vaccine is the hepatitis B virus vaccine.
There are 4 main types of vaccines: 1  live attenuated vaccines, which contain a living, but weakened, form of the germ (organism); 2  inactivated vaccines, which contain a killed form of the organism; 3  subunit vaccines, which contain just the part of the organism that stimulates an immune response (the antigen); and.n antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells â another type of immune system cell that helps protect against disease â is also important for some vaccines.
